How about we blame good old fashioned stupidity?
Yes, I could go with that. There must have been something around the house--even a cute hat--that this cretin could have used to have some decent hair for others to view for the working day, until she could stop off on her way home from work and replace the hair spray she ran out of. I also see that she did her eye makeup in such a way that she resembles a clown. So obviously, she is not very up on the proper use of beauty products. And just as obviously, she is, as you say, really stupid.
